Black Rage (Ex): Every time you are hit for at least 10% of your maximum health you gain a "vengeance charge", for every 5% beyond the initial 10% you gain an additional charge. Each vengeance charge increases your melee damage by 1(this damage is not multiplied by criticals). These charges last 1 round per level plus your strength mod. You may have a maximum number of vengeance counters equal to your unmodified strength or constitution score(whichever is higher).

Retribution Shield (Sp): When dealt damage in melee the knight may unleash electric vengeance upon his foe. For every 5% of his maximum health taken in damage, the knight can automatically deal 1d6 electricity damage and may increase the damage by spending vengeance charges, each charge spent adds 1d6 electricity damage, and the damage caps at 11d6(total damage not just bonus). Plus while active the knight gains electricity resistance equal to 5 plus his knight level + his current amount of vengeance charges. Using this ability costs 2 mana and lasts for 1 round per level plus one round for every vengeance charge the knight has at the time of casting. This is equivalent to a 2nd level spell.

Electric Purge (Sp): This spell deals 1d4 electric damage per level to everything in 10 feet(including knight) plus 2d4 electric damage per vengeance charge spent. The dice cap is equal to the knights constitution score. The knight regains lost vengeance charges from this damage but at a slower rate than normal. For every 10% of his health dealt by this ability, he gains one vengeance charge. This ability costs 5 mana to use and is considered a 3rd level spell.

Winds of the Storm (Sp): The knight may cast Defenestrating Sphere as the spell.

Vengeful Casting (Su): The Ebon Knight may substitute up to 50%(rounded down) of a mana cost with vengeance counters.

Fury of Crosis (Su): Once per encounter as a free action, when the knight is at 50% or less health. The knight gains vengeance counters at a rate of 2 per round and gain an additional vengeance counter every time you would gain one from another source. He also gains immunity to mind affecting effects and electricity, and gains a +2 sacred bonus to str dex and con. Lasts 2 rounds plus the knight's constitution bonus.

By disobeying a tenet of Crosis the knight is cast from the ranks and becomes an ex knight. Ex knights are never allowed into the city of Braxis and if spotted by another ebon knight they will come under attack
